Richard Fitzgerald 9ddae9dad0 soundwire: bandwidth allocation: Use hweight32() to calculate set bits
Replace the call to sdw_ch_mask_to_ch() with a call to hweight32().

sdw_ch_mask_to_ch() is counting the number of set bits. The hweight()
family of functions already do this, and they have an advantage of
using a bit-counting instruction if it is available on the target CPU.
This also fixes a potential infinite loop bug in the implementation of
sdw_ch_mask_to_ch().
